Air conditioning for extensions and kitchen-diners in Norwich
In Norwich, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat.
For a kitchen-diner in Norwich, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Norwich and the rest of Norfolk, including Great Yarmouth and King's Lynn. Homes in NR2 and NR3 are all within our coverage.
Prices in Norwich
Budget around £1,595–£4,995 per space including VAT for air conditioning for extensions and kitchen-diners in and around Norwich. Prices here sit above the national middle, reflecting East of England labour rates and parking and access costs. What moves a quote in Norwich up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,295–£3,195 here.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
